[1] On January 1, 2020, the Company adopted ASU 2016-13; see Note 1.

The balance as of January 1, 2020 in the Net unrealized gains (losses) on investments with OTTI losses column is now reported in the Net unrealized gains (losses) on other investments column. Prior period amounts were not adjusted for the adoption of this standard.
